The strip is provided with a relatively broad raised tenon 7. This tenon is formed by bending the metal of the strip. The tenon runs lengthwise the strip along its centre or at such points so far removed from the sides of the strip that it will lie fully contained within any joint vitt awhen tne iri ititath ists ee nr viq stwith ee reiere lv. ewats l in; dined? t snaq jifitetval lir uehe .iisl e te.

' e tiii b ei tel;- -Pheeee in a horizontal direction and' looped bali' itself to form a socket-forming member 15 within which the tongue 13 on the'end of an adjacent strip is contained for forming the interlocking connection between adjacent strips when the strips are brought into proper alignment with one another.

10, the metal -of the strip being bent to form gutters crossing the flashing at intervals with extension throughthe tenons by which water may passfrom one side of the flashing to the. other, the gutters imparting, also, the ends 10 to the raised tenons. The flashing joints between i.

the strips lie well above the bodies of the strips. Gutters are provided on the respective strips at points adjacent the flashing joints between them,

the joints lying well above these gutters. and immediately above one of the gutters. Consequently, in order for moisture or water to pass through the flashing at the points of the joints between its strips the water must pass upwardly by the freeend of thesocket-forrning member 15, thence through the socket and upwardly by the free end of the tongue 13. Such passage of water is practically impossible inasmuch as it cannot flow upwardly. Instead any water which might accumulate at the points of the flashing joints'will passjoff into one or the other of the adjacent gutters,- while any water which might accumulate on the under side of the socket-forming members'l5 will pass off the free end of this member into the gutter below.

Not only does the raising of the flashing joints above the bodies of the"str ips possess the advantage of preventing passage of water through the strips-atthe pointsof the joints, but a further material advantage is obtained. As previously described, the flashing is often made wider than the width of the wall with flanges bent upwardly or downwardly to bear against the face or faces ofthe wall as shown in Figs. 3 and 6. By raising the flashing joints above the bodies of thestrips, as they are in fact raised by the strip portions 12 and 14 respectively, the bodies of the strips may'then be initially formed with flanges and the interlocking joint continued; aroundthe bend for making the flanges, after whichathe individual units may hei -applied to the wall'and locked together. The making of a" bend in the strip-for forming the flange tends to flatten the 1 socket which receives the tongue,

preventing entrance of the tongue, and if the joint is not raised this-would be the effect and the flange 5 could; only be formed after the strips have been applied to the wall and locked together; By raising the joint any distortions arising from the bending for forming the flange will concentrate on the strip portions 12 and 14 which carry the joint and these portions will'become' more or less flattened but the joint itself will be left intact. i

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States:

' 1; A; flashing comprising connected strips of sheetjmetal bent toform a series of raised tenons removed from the sides of the flashing with extension longitudinally thereof each of said tenons having sides and ends, the metal of the strips being also bent to form gutters crossing the flash-,

ing at intervals with extension through the tenons whereby said ends will be imparted to the tenons, and means connecting said strips.

2. A flashing comprising end connected strips of sheet metal bent to form a series of raised tenons removed from the sides of the flashing with extension longitudinally thereof, the metal of the strips being also bent to form gutters crossing the flashing with extension through. the tenons, said gutters being located on separate strips at points adjacent the connected ends thereof, and interlocking members forming the end connection between the strips and located above said gutters,

the metal of the respective strips extending from said. guttersto form said interlocking members.

3. A flashing comprising end connected strips of sheet metalbent to form a series of raised tenons removed from the sides of the flashing Qwith extension longitudinally thereof, the metal of the strips being also bent to form gutters crossing the flashing with extension through the tenons, said gutters being located on separate strips at points adjacent the connected ends thereof,- and interlocking members comprising a tongueanda socket-forming member in which said tongue is contained forming the end connection between said strips and located above said gutters, the metal of the respective strips extending from said gutters to formsaid tongue and socketforming member respectively.

4. A flashing comprising a strip of sheet metal bent to form a raised tenon removed from the sides of the'flashing with extension lengthwise thereof, the metal of the strip being also bent to form gutters crossing the strip with extension and members borne by the strip at the respective ends thereof adapted to form interlocking connection with members on the ends of adjacent strips, said members borne by the strip being formed by extending the metal of the strip from the respectve gutters; i r

5. A flashing comprising a'strip of sheet metal bent to form a raised tenon removed fromthe sides of the flashing- -withextension lengthwise thereof, the metal of the strip being also bent to form gutterscrossing the strip with extension through the tenon adjacent the endsof the strip, a tongue borne by the strip at one end, and a socket-forming member borne by the strip at its opposite ends, said tongue and socket-forming member being formed respectively by extending the metal of the strip from the respective gutters to which the tongue and socket-forming member lie adjacent.

6. A flashing comprising end connected strips of sheet metalwith turned flange extending from said'strips at'the side thereof, interlocking mem} is continued through said flange, and. strip por-'- tions raising the interlocking members forming said joint above the bodies of the strips whereby saidjoint will be left intact and said. tongue maythrough the tenon adjacent the ends of the strip,
